How to calibrate the imu data of totalcapture? #28

Hi, thanks for your excellent work. Now I have the raw totalcapture datasets in https://cvssp.org/data/totalcapture/ and the smpl gt data in https://dip.is.tuebingen.mpg.de/ . The TotalCaptureReal.zip only contains calibrated 6 imu data. I want to use the other imu for my work. I have tried the method in "Real-Time full-body motion capture from video and IMUs". The formula is $R{b{i}}^{g}=R{i g} \cdot R{i} \cdot R{i b}^{-1}$ where R_ig and R_ib are in _calib_imu_ref.txt and _calib_imu_bone.txt respectively. But the result is wrong in visualization. I also tried the calibration procedure mentioned in dip paper, and the result is wrong. Maybe I missed something important. Would you help me provide the critical code for calibrating the imu ori and acc ? Thank you very much!
